Endoscopic Retrograde Cholangio-Pancreatography (ERCP)

An ERCP is a special technique for studying the bile ducts, pancreatic duct and gallbladder. An endoscope is passed through the mouth, esophagus stomach, and into the first part of the small intestine. Then, a contrast material (dye) is injected into the pancreatic or biliary ducts so that X-rays may be taken. Your doctor might apply a local anesthetic to your throat and/or give you a sedative to make you more comfortable.
